[ Upstream commit 79a7482249a7353bc86aff8127954d5febf02472 ]
Both cxgb4 and csiostor drivers run on their own independent Physical
Function. But when cxgb4 and csiostor are both being loaded in parallel via
modprobe, there is a race when firmware upgrade is attempted by both the
drivers.
When the cxgb4 driver initiates the firmware upgrade, it halts the firmware
and the chip until upgrade is complete. When the csiostor driver is coming
up in parallel, the firmware mailbox communication fails with timeouts and
the csiostor driver probe fails.
Add a module soft dependency on cxgb4 driver to ensure loading csiostor
triggers cxgb4 to load first when available to avoid the firmware upgrade
race.

[ Upstream commit 51032e6f17ce990d06123ad7307f258c50d25aa7 ]
The e100_get_regs function is used to implement a simple register dump
for the e100 device. The data is broken into a couple of MAC control
registers, and then a series of PHY registers, followed by a memory dump
buffer.
The total length of the register dump is defined as (1 + E100_PHY_REGS)
* sizeof(u32) + sizeof(nic->mem->dump_buf).
The logic for filling in the PHY registers uses a convoluted inverted
count for loop which counts from E100_PHY_REGS (0x1C) down to 0, and
assigns the slots 1 + E100_PHY_REGS - i. The first loop iteration will
fill in [1] and the final loop iteration will fill in [1 + 0x1C]. This
is actually one more than the supposed number of PHY registers.
The memory dump buffer is then filled into the space at
[2 + E100_PHY_REGS] which will cause that memcpy to assign 4 bytes past
the total size.
The end result is that we overrun the total buffer size allocated by the
kernel, which could lead to a panic or other issues due to memory
corruption.
It is difficult to determine the actual total number of registers
here. The only 8255x datasheet I could find indicates there are 28 total
MDI registers. However, we're reading 29 here, and reading them in
reverse!
In addition, the ethtool e100 register dump interface appears to read
the first PHY register to determine if the device is in MDI or MDIx
mode. This doesn't appear to be documented anywhere within the 8255x
datasheet. I can only assume it must be in register 28 (the extra
register we're reading here).
Lets not change any of the intended meaning of what we copy here. Just
extend the space by 4 bytes to account for the extra register and
continue copying the data out in the same order.
Change the E100_PHY_REGS value to be the correct total (29) so that the
total register dump size is calculated properly. Fix the offset for
where we copy the dump buffer so that it doesn't overrun the total size.
Re-write the for loop to use counting up instead of the convoluted
down-counting. Correct the mdio_read offset to use the 0-based register
offsets, but maintain the bizarre reverse ordering so that we have the
ABI expected by applications like ethtool. This requires and additional
subtraction of 1. It seems a bit odd but it makes the flow of assignment
into the register buffer easier to follow.

e100_get_regs_len and remove a double 'divide and then multiply'
calculation that the e100_reg_regs_len function did.
This change broke the size calculation entirely as it failed to account
for the fact that the numbered registers are actually 4 bytes wide and
not 1 byte. This resulted in a significant under allocation of the
register buffer used by e100_get_regs.
Fix this by properly multiplying the register count by u32 first before
adding the size of the dump buffer.

Thomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglx
that our handling of the hrtimer here is wrong: If the timer fires
late (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot)
then it tries to actually rearm the timer at the next deadline,
which might be in the past already:
1 2 3 N N+1
| | | ... | |
^ intended to fire here (1)
^ next deadline here (2)
^ actually fired here
The next time it fires, it's later, but will still try to schedule
for the next deadline (now 3), etc. until it catches up with N,
but that might take a long time, causing stalls etc.
Now, all of this is simulation, so we just have to fix it, but
note that the behaviour is wrong even per spec, since there's no
value then in sending all those beacons unaligned - they should be
aligned to the TBTT (1, 2, 3, ... in the picture), and if we're a
bit (or a lot) late, then just resume at that point.
Therefore, change the code to use hrtimer_forward_now() which will
ensure that the next firing of the timer would be at N+1 (in the
picture), i.e. the next interval point after the current time.

Fan speed minimum can be enforced from sysfs. For example, setting
current fan speed to 20 is used to enforce fan speed to be at 100%
speed, 19 - to be not below 90% speed, etcetera. This feature provides
ability to limit fan speed according to some system wise
considerations, like absence of some replaceable units or high system
ambient temperature.
Request for changing fan minimum speed is configuration request and can
be set only through 'sysfs' write procedure. In this situation value of
argument 'state' is above nominal fan speed maximum.
Return non-zero code in this case to avoid
thermal_cooling_device_stats_update() call, because in this case
statistics update violates thermal statistics table range.
The issues is observed in case kernel is configured with option
CONFIG_THERMAL_STATISTICS.

When PN checking is done in mac80211, for fragmentation we need
to copy the PN to the RX struct so we can later use it to do a
comparison, since commit bf30ca922a0c ("mac80211: check defrag
PN against current frame").
Unfortunately, in that commit I used the 'hdr' variable without
it being necessarily valid, so use-after-free could occur if it
was necessary to reallocate (parts of) the frame.
Fix this by reloading the variable after the code that results
in the reallocations, if any.

commit 0f36b88173f028e372668ae040ab1a496834d278 upstream.
If driver read val value sufficient for
(val & 0x08) && (!(val & 0x80)) && ((val & 0x7) == ((val >> 4) & 0x7))
from device then Null pointer dereference occurs.
(It is possible if tmp = 0b0xyz1xyz, where same literals mean same numbers)
Also lm75[] does not serve a purpose anymore after switching to
devm_i2c_new_dummy_device() in w83791d_detect_subclients().
The patch fixes possible NULL pointer dereference by removing lm75[].

commit 80f6e3080bfcf865062a926817b3ca6c4a137a57 upstream.
If the file size is almost S64_MAX, the calculated number of Merkle tree
levels exceeds FS_VERITY_MAX_LEVELS, causing FS_IOC_ENABLE_VERITY to
fail. This is unintentional, since as the comment above the definition
of FS_VERITY_MAX_LEVELS states, it is enough for over U64_MAX bytes of
data using SHA-256 and 4K blocks. (Specifically, 4096*128**8 >= 2**64.)
The bug is actually that when the number of blocks in the first level is
calculated from i_size, there is a signed integer overflow due to i_size
being signed. Fix this by treating i_size as unsigned.
This was found by the new test "generic: test fs-verity EFBIG scenarios"
(https://lkml.kernel.org/r/b1d116cd4d0ea74b9cd86f349c672021e005a75c.1631558495.git.boris@bur.io).
This didn't affect ext4 or f2fs since those have a smaller maximum file
size, but it did affect btrfs which allows files up to S64_MAX bytes.

For DEV_VER_V3 version there exist race condition between clearing
ep_sts.EP_STS_TRBERR and setting ep_cmd.EP_CMD_DRDY bit.
Setting EP_CMD_DRDY will be ignored by controller when

a small time gap in which the EP_STS_TRBERR can be set. In such case
the transfer will not start after setting doorbell.

[ Upstream commit 3b0c406124719b625b1aba431659f5cdc24a982c ]
This issue happens when a userspace program does an ioctl
FBIOPUT_VSCREENINFO passing the fb_var_screeninfo struct
containing only the fields xres, yres, and bits_per_pixel
with values.
If this struct is the same as the previous ioctl, the
vc_resize() detects it and doesn't call the resize_screen(),
leaving the fb_var_screeninfo incomplete. And this leads to
the updatescrollmode() calculates a wrong value to
fbcon_display->vrows, which makes the real_y() return a
wrong value of y, and that value, eventually, causes
the imageblit to access an out-of-bound address value.
To solve this issue I made the resize_screen() be called
even if the screen does not need any resizing, so it will
"fix and fill" the fb_var_screeninfo independently.

This patch adds the missing NULL termination to the "bpf" and
"perf_event" object class permission lists.
This missing NULL termination should really only affect the tools
under scripts/selinux, with the most important being genheaders.c,
although in practice this has not been an issue on any of my dev/test
systems. If the problem were to manifest itself it would likely
result in bogus permissions added to the end of the object class;
thankfully with no access control checks using these bogus
permissions and no policies defining these permissions the impact
would likely be limited to some noise about undefined permissions
during policy load.

If NETIF_F_GRO_FRAGLIST or NETIF_F_GRO_UDP_FWD are enabled, and there
are UDP tunnels available in the system, udp_gro_receive() could end-up
doing L4 aggregation (either SKB_GSO_UDP_L4 or SKB_GSO_FRAGLIST) at
the outer UDP tunnel level for packets effectively carrying and UDP
tunnel header.
That could cause inner protocol corruption. If e.g. the relevant
packets carry a vxlan header, different vxlan ids will be ignored/
aggregated to the same GSO packet. Inner headers will be ignored, too,
so that e.g. TCP over vxlan push packets will be held in the GRO
engine till the next flush, etc.
Just skip the SKB_GSO_UDP_L4 and SKB_GSO_FRAGLIST code path if the
current packet could land in a UDP tunnel, and let udp_gro_receive()
do GRO via udp_sk(sk)->gro_receive.
The check implemented in this patch is broader than what is strictly
needed, as the existing UDP tunnel could be e.g. configured on top of
a different device: we could end-up skipping GRO at-all for some packets.
Anyhow, that is a very thin corner case and covering it will add quite
a bit of complexity.

- hopefully clarify the commit message

The device size calculation was done before processing the loop
configuration, which meant that the we set the size on the underlying
block device incorrectly in case lo_offset/lo_sizelimit were set in the
configuration. Delay computing the size until we've setup the device
parameters correctly.

When LOOP_CONFIGURE is used with LO_FLAGS_PARTSCAN we need to propagate
this into the GENHD_FL_NO_PART_SCAN. LOOP_SETSTATUS does this,
LOOP_CONFIGURE doesn't so far. Effect is that setting up a loopback
device with partition scanning doesn't actually work when LOOP_CONFIGURE
is issued, though it works fine with LOOP_SETSTATUS.
Let's correct that and propagate the flag in LOOP_CONFIGURE too.

When testing ION, we often see warnings in dmesg where a
mid-order allocation failed. The logic will always fall back to
lower-order allocations (there is no strict need to return
contiguous pages) so these warnings are distracting noise.
To solve this, this patch adds the __GFP_NOWARN flag to all
mid-order allocations.
